Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544150, here are decompositions:

19 + 31544131 = 31544150
61 + 31544089 = 31544150
73 + 31544077 = 31544150
97 + 31544053 = 31544150
109 + 31544041 = 31544150
139 + 31544011 = 31544150
163 + 31543987 = 31544150
223 + 31543927 = 31544150

Showing the first eight; more decompositions exist.
